Answer:
x ≈ 6.6, y ≈ 13.3
Step-by-step explanation:
Using the tangent ratio in the right triangle to find x
tan30° = =
=
( multiply both sides by 11.5 )
11.5 × tan30° = x , then
x ≈ 6.6 ( to the nearest tenth )
Using the cosine ratio in the right triangle to find y
cos30° = =
=
( multiply both sides by y )
y × cos30° = 11.5 ( divide both sides by cos30° )
y = ≈ 13.3

Answer:
B and F
Step-by-step explanation:
The simple golden rule that we need to know here is
<em><u>"The probability of any event is always between 0 and 1 inclusive"</u></em>
<em><u /></em>
If an event has a probability of p(x), we can say:
Also, probability is ALWAYS POSITIVE.
Thus,
A) OK because 33.3% is 0.333, which is between 0 and 1
B) NOT OK, because probability isn't negative
C) 0.0002 is in between 0 and 1, so possible
D) 0 probability means it can't happen, so that's okay as well
E) this is a fraction with numerator less than denominator, which means its between 0 and 1, so OK
F) this fraction's numerator is greater than denominator, so it's greater than 1. Probability can't be greater than 1, so NOT OK
Out of these B and F cannot represent the probability of an event
